How evolution works

I understand that goal oriented descriptive language is just a
metaphor and I myself use such language all the time, but it
vaguely disturbs me nonetheless. It is a common and relatively
harmless habit to get into as long as we remember that evolution
only looks goal oriented in hindsight. Actually natural selection
is thrashing about blindly looking for what works - Hah! There I
did it myself.
I'm still trying to find my copy of The Moon is a Harsh Mistress - I
just moved.
